Traveling is fun, but an insufficient communication environment can be a problem. Especially for those who are traveling to Japan, how to purchase and use a SIM card is a very important issue. So this time, we will explain in detail how to choose and purchase a Japanese SIM card. There are also rules unique to Japan, so please use this article as a reference to enjoy your trip.

Why do you need a SIM card?

For foreign travelers visiting Japan, a stable communication environment is essential. There is no doubt that a smartphone is useful when opening a map app or looking up information on tourist spots while traveling. However, if you continue to use the communication service you have contracted in your home country, you may be charged very high fees. Therefore, in order to enjoy your trip to Japan comfortably, it is common to use a local SIM card.

To avoid high communication fees

If you use your home country’s communication plan as it is while staying in Japan, international roaming fees will be applied and large communication fees may be incurred. To reduce this burden, it is recommended to use a local SIM card. Japanese SIM cards are subject to local charges, so you can connect to the Internet at a low cost. Local communication plans are an economical option, especially for long-term residents and travelers who use a lot of data.

Risk of international roaming charges

With international roaming, you can expect high charges for calls, messaging, and Internet use. To avoid the risk of paying huge amounts without knowing it, it is essential to have a SIM card that is compatible with Japan’s communication environment.

Differences between short-term travelers and long-term residents

For short-term trips, prepaid SIM cards are convenient. On the other hand, if you are staying for more than a month, SIM cards with monthly plans are more economical. You need to choose the one that suits your needs.

To ensure smooth communication

Using a SIM card that is compatible with Japan’s radio wave environment will significantly improve the stability of your communication. In particular, high-speed data communication is possible in urban areas, and a major advantage is that you can connect to the Internet without stress even while moving around in tourist areas. This allows you to search for map apps and tourist information smoothly, greatly reducing stress during your trip.

Differences in data communication speeds

Overseas communication plans may limit communication speeds in Japan. By switching to a Japanese SIM card, you can easily handle data-intensive tasks such as video streaming and SNS posting.

Call function also covered

If you want to call local restaurants or tourist spots while traveling, using a local SIM card will keep your calling charges low. In particular, creating an environment where you can contact them quickly in an emergency will give you peace of mind.

How to choose a Japanese SIM card

There are many different options for SIM cards available in Japan, each with different characteristics. Choosing a SIM card that suits your travel style and communication needs will make your stay more comfortable.

Data communication volume

When choosing a SIM card, the first thing to consider is the amount of data communication. The activities that travelers perform on their smartphones may require a large amount of data communication. For example, if you frequently do live streaming at tourist spots or post in real time on social media, it is safe to choose a large-capacity data plan. However, the more data you use, the higher the price, so it is important to choose a plan that suits your purpose.

Choose a plan according to your purpose

Watching videos and games: Choose a high-speed, large-capacity plan.
Only using maps and messaging apps: A small-capacity data plan is sufficient.
Based on these criteria, choose the best SIM card.

Network coverage

The coverage of SIM cards in Japan varies depending on the carrier. Most SIM cards can be used without problems in urban areas and tourist spots, but in rural and mountainous areas, only certain carriers may be compatible. Therefore, it is important to choose a SIM card taking into account the geographical conditions of your travel destination.

Urban vs. Rural

In urban areas, all carriers provide high-quality communication. On the other hand, travelers who mainly visit rural areas are better off with a SIM card that covers a wide area.

Support status for each tourist spot

For example, if you are visiting Mt. Fuji or the natural areas of Hokkaido, it is convenient to use a SIM card provided by a specific operator. We recommend that you check the coverage area before purchasing.
